Of course, if I delete some components on the table, the pagination is quite faster since less information is displayed.

But...

For instance, when we use the pagination through the rich:datascroller, on IE7 it takes like 1 second more than other browsers to display the next page. The ajax request is fired but we noticed that the browser is like "blocked" before displaying the next page. With other browsers, even IE6, this doesn't happen. I used a javascript debugger but i didn' t find anything "strange", the javascript functions seem to be ok and not "blocking" the browser.

We know that IE7 is worse than other browser, but I would like to know if someone has the same problem.
